Transponder Chip
In cars made after 1995, a small electronic chip called transponder is integrated into the head of your car key. It is also referred to as a "chip key" or a "transmitter-responder" key. Its goal is to prevent the engine from starting when another person has a duplicate of your key. It works by sending the radio frequency signal from the key to the immobiliser system of your car. If the code stored in the car's computer is in line with the signal transmitted by the key, it will disable the immobiliser and allow the engine to begin.
The key that is equipped with a transponder chip is often referred to as a 'fob' or a smart key because it is more difficult to copy than a traditional mechanical key. It is possible to duplicate a conventional key but not a transponder one. In contrast to the central locking element remote of a standard key which is powered by batteries, a transponder chip powered by an infrared (IR) signal transmitted through the antenna ring on the ignition cylinder.
To activate the transponder chip the ignition cylinder has to be turned to the ON position. The ring emits a burst of IR energy that is picked up by the microchip within the key. The chip then responds with an unique code to the immobiliser of your car. The car's computer compares the code stored in its memory to the transponder's and If the two codes are identical, it will start the engine.
The immobiliser shuts down the engine in the event of an unauthorised key or transponder. It also stops any vital components of the car from working. The car will not move when the engine isn't working. It would be easy for criminals to wire it to drive away.

Security Light
The immobiliser makes use of a tiny battery to send an electrical signal to the chip that is in your key. This is an anti theft device that blocks anyone from opening your vehicle without the proper key. If the system cannot identify a digital serial number from the chip in your key it will disengage the engine immobiliser and stop the car from getting started.
The car immobiliser is a great method of deterring thieves, but it can occasionally be out of the sync. This can be caused by interference or the system becoming too sensitive. This could require a reset. To do this simply disconnect the battery. After 15 minutes, reconnect the battery and then restart the car. This will reset the system and make it ready to accept the key again.
The security light is the vehicle immobiliser's method of letting you know that there's a problem with the system. If the light is on and you try to start your car, it means that the code that is stored in the ECU is not compatible with the chip inside the key. This could happen if you have recently replaced your car key with one that isn't programmed to the vehicle, or in the event that you've had a defective swapped ECU.
If this is the situation, it's best to take your key or transponder chip to a professional to get them correctly programmed for the vehicle you are driving. It is possible that the system won't accept the key because of a software update or glitch. To test, put your key in the ignition and turn it to the ON position. Do not try to start the car. Let the key stay in this position for ten minutes. This should cause the security light to light up and then to go off.

Programming
The car immobiliser prevents the engine from running when the fob or key are not programmed correctly. It uses a special RFID micro-chip that can't be duplicated and comes with its own digital serial number. The immobiliser will stop working if it does not recognise the code. It's difficult to beat.
Modern cars are equipped with this security system as standard. This makes it extremely difficult to hot-wire the car or use a different key for starter. The system operates by sending a passcode from the key fob to the ECU. The ECU knows it's the correct key and that it doesn't have to been compromised code. The system won't permit the vehicle to start if it doesn't have the correct code. Some models will even report back to the owner if a person tries to use an incorrect fob or key.
However the system isn't completely secure. Certain thieves have been able to get around the immobiliser using methods such as 'hot-wiring'. This involves crossing the wrong wiring in a vehicle in order to cause a malfunction in the ECU. But, this technique is quite risky and requires a great deal of experience in order to do it without cutting yourself. Additionally, many modern car thieves have shifted to more sophisticated methods such as using specialised apps or Bluetooth to hijack the car's data and then remotely control it via their phones.
Car owners often notice warning lights that signal an immobiliser malfunctioning. It can occur for a variety of reasons, but one of the most common is a faulty or dead battery on the key fob. This issue can be resolved by a simple replacement.
If this doesn't work, the transponder chip might be defective or not compatible with the ECU. This is more difficult to diagnose and fix and may require a specialist locksmith for cars or a dealership.
